OK, so it seems from my research so far that:
a) 'Isochronous mode' is a USB 2.0 and above thing
No. The programming model has not changed in USB 2.0. The difference is
mostly one of electrical specifications and speeds.
b) Sun Ray 2 only has 1.1 USB ports
IIRC it is a bit more complicated. But that is not my area of expertise.
... so that precludes hanging an iPhone off a Sun Ray 2.
If it only needs USB 2.0 compatibility it might work. If it needs
isochronous transport it does not work (today). If it needs USB 2.0 data
rates, it will never work with a Sun Ray 2.
A Sun Ray 3 Plus has USB 2.0 ports and therefore might support
isochronous devices, if the rest of the stack supported it. Any Oracle
person got an opinion on whether it's on a drawing board somewhere?
It might even be possible with older DTUs.
But I neither know, if it is on any actual roadmap, nor if it would
include Sun Ray 2/2FS/270.
And if I knew, this list wouldn't be an appropriate place to discuss it :-/
